Three quakes were recorded Wednesday, the largest being a magnitude-3.5 that struck at 7:32 a.m. and was centered under Lani Kai Drive, the geological survey said. It was preceded by a 3.2 quake at 7:01 a.m. centered on Oakmead Drive and was followed by a 2.6 quake at 7:35 a.m. centered on Laguna Circle.

There were no immediate reports of damage.

All of the earthquakes were centered around the Concord-Green Valley Fault, the same fault linked to a series of quakes that hit Sunday and Monday. The largest of those measured 3.6.

Seismologists have said that they will be examining whether the quakes were related to August’s magnitude 6.0 South Napa quake. The last big earthquake along the Green Valley Fault occurred before 1770, but it’s part of a fault system that starts in Concord and runs past Lake Berryessa, scientists say.
